Metals, Nonmetals
and Metalloids
Metals
Physical Properties :

Shiny Luster
Malleable
Ductile
Conductivity
Magnetism
Malleable
A malleable
material is one
that can be
pounded into
shapes
Ductile
A ductile
material is one
that can be
stretched into a
thin wire.
Conductivity
A good conductor
allows heat and
electricity easily to
pass through the
material
Magnetism
Materials that are attracted to magnets
and can be made into magnets are called
magnetic.
Nonmetals
Physical Properties:
• Dull Luster
• Not conductors
• Brittle- not malleable
• Not ductile
Metalloids
Metalloids can have properties of
both metals and nonmetals.
Silicon is a metalloid. Silicon
is brittle like a nonmetal but can
conduct electricity like a metal.
Silicon is found in computer chips,
glass and sand.
